The size of the canopy does not affect how quickly the parachute falls to the ground. The results showed that the small canopy (5cm x 5cm) fell to the ground the quickest and the larger canopy (20cm x 20cm) took the longest to fall to the ground. The results of my experiment fail to support my hypothesis. I have learned that the reason the smaller canopy was able to fall quick is because it has a smaller surface area which means that there is less air resistance pushing up on the canopy and slowing it down as it falls to the ground.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
